Safety contactor SB is not reporting its state properly, indicating a wrong feedback connection.

: The landing lock or car gate contact was broken while the elevator was moving. This is a high-priority safety fault that halts the car immediately to prevent injury. Error 0004 (Door Stopped Out of Door Zone)

Dealing with a elevator that’s flashing error codes? You’re likely looking at a system controlled by the Schindler 5500 MMB (Modular Main Board) or a similar frequency converter setup. A specific quirk of the Schindler 5500 involves

The configuration data stored on the SIM card/chip does not match the controller board hardware configuration. Cause: Swapped boards or improper commissioning.

frequently precedes a system breakdown (Error 1680) and may indicate wiring faults or governor tension switch issues. 00 Series (Critical Safety): Low-digit codes often point to fundamental failures. 02 / 0002: Safety contactor SB is not reporting its state

Cause: Short circuit in the motor windings, short to ground, or a locked rotor/stuck brake.

: A common 5500 fault where the system time does not match, which can block operations. Access the Main Menu > Parameter > Date Time and update to the current values. Special Unit Maintenance LMS (Load Measuring System)
